HEATING-STOVE;

SPECIFICATION forming artof Letters Patent Nd. 734,460, dated. T1113? i,1 903. Application filed November 2 4, 190 2)" Serial No. 132,538. (Nomodel.)

Chicago, in the State of Illinois, have in-.

vented certain new and useful Improvements in Heating-Stoves, of whichthe following is a specification.

The invention relates to gas-stoves used chiefly for warming purposesand having an interior and an exterior casing; andthe ob ject of theimprovements is to provide means for producing a circulation of heatedcurrents of air within the interior casin g and discharging the sametherefrom near the bottom into the exterior casing and there mixing thesame with air drawn into the exterior from the outside and escapingthrough the top of the exterior casing. I have attained this object inthe stove constructed as illustrated in the accompanying drawing, whichis a vertical central sectionof the same.

In the drawing, A is the exterior casing, preferably cylindrical in formand secured to a bottom plate B, having lugs b, through which and thecasing rivets are applied, and to a top plate 0, having lugs c, in'asimilar manner. 4

D is a perforated top piece adapted to fit over the top of the exteriorcasing. v

E is the interior casing, which is provided with a series of conicdeflectors E, open at' the top and secured to the casing inside at e bymeans of rivets. The deflectors are provided near the base withahorizontal row of perforations e. The interior casing is held in placebetween the plates B O by means of lugs b 0, so as to provide open spaceF between it and the exterior casing. Openings 6 in the interior casingat the part near the base of the lowermost deflector and extends ingclear around the casing are provided,

supported on the base-plate g andconnected with the gas-supply pipe GThe plate Bis hinged at b to the stovebase and has a large centralopening sufficient to pass over the burner when the stove is turned overon the hinge. The plate B and baseplate 9 also'have an annular row ofholes a, through which the space F communicates with the atmosphereunder the stove-base. An ornamental piece or foot-rail is attached nearthe base of the outer casing.

The top plate 0' may be provided with a large central opening at o o tobe stopped by a suitable cover. This opening should remain-closed alwayswhile usingthe stove as a heater. The top D may be lifted off.

In operation the stove is turned over on the hinge at b to afford accessto the burner in lighting the gas. The air to the burner passes inthrough the large central opening at g and the ascending heated airpasses out of the deflectors at the openings in the top thereof in acolumn central to the interior casing, impinges the plate (1, thendescends next to the wall of the interior casing, passing through theopenings e, next passes out through the openings 6 into the lowerportion of the space F, and thence up through openings f and out throughthe perforated top D. By this operation an increased upward draft iscreated'in the spaces F, which causes the outer atmosphere down near thefloor to be drawn in through the openings a a and mixed with the currentthus circulated through the interior casing and intensely heatedthereby. The air being drawn in at the central opening to the burner atthe base of the stove is intensely heated while ascending and thenpassed outwardly and down along the wall within the interiorcasing,causing it to be highly heated, and the air near the floor taken inthrough the openings 1. In a heating-stove of the class described thecombination with an exterior casing provided with a perforated portionextended around near the base and open at the top, of an interior casingprovided with a perforated portion extended around near the base andclosed at the top, and a series of conic deflectors open at the top andprovided with a row of perforations near the base, the said deflectorsbeing arranged one above the other within the interior casing, the baseof the deflectors fitting closely therein as specified.

2. In a stove of the class described the base provided with a largecentral opening and a burner over said opening, in combination with anexterior casing having a perforated portion extended around the samenear the base and being open at the top, an interior casing having aperforated portion extended around the same near the base and beingclosed at the top, and a series of conic deflectors open at the top,provided with a row of perforations near the base, and closely fittedwithin the interior casing as specified.

3. In a stove of the class described the base provided with a largecentral opening, an annular row of openings near the outer edge, and aburner over the central opening, in combination with an exterior casinghaving a perforated portion extended around the same near the base andbeing open at the top, an interior casing having a perforated portionextended around the same near the base and being closed at the top, anda series of conic deflectors open at the top, provided with perforationsat the base and closely 35 fitted within the interior casing asspecified.
